Pretzels? LOL! I've never heard those as being thought of as an American snack ;D They've always been sort of an afterthought to me. Like, I'll never outright buy them at the store, but if someone has them at their house I'll eat a few.
I've noticed here though, that a lot more people are saying "fish and chips" (on like dinner Menus and such) instead of the usual "fish dinner" or "fish and fries", which I find very interesting! Maybe they're trying to be more exotic?
